PIC18F2550 Problem

[dmitri]

My pic is programed ? But when I disconnect the USB and the ICSP, and when I reconnect the USB, my computer don't propose to install driver.

Drivers are already in OS so it doesn't have to install it.

Yes, but when I connect megadrum usb to my computer, I haven't any reaction.

That is ok. What reaction do you expect?

Computer must find "MEGADRUM" isn't it ?

It work the first time, but not now anymore.

Judging from what you say it already found it.

I don't think because I haven't got the midi port of the megadrum active. When I first connect megadrum to usb, computer find megadrum, and install drivers for the usb port.

I connect the megadrum with "good" program in the 18f2550, and no reaction. That's why I think programmation don't work correctly and my pic is incorrect.

Again, it finds drivers and tells about it only one time - the first time.

Yes, I know, but when I'm going in the list of peripheral, there isn't the megadrum.

When I connect it to my computer, it sound the usb connect and just after the usb disconnect. So there is a problem.

[dmitri]

If it disconnects straight after it connects than it is a problem with the connection - wires, tracks, cable. Or you are describing the problem not exactly as it happens.

[eloma33]

no problem with the usb cable, i used it with other periphal, and all is ok.

[eloma33]

BINGO !!! YES It works fine !!!

Now I have to program the ATMEGA !!! wish me luck !!!

How to be displayed on the LCD when 18F2550 is programmed ?

Since the beginning, my LCD is on (blue light) and all the alpha-numéric zone on the first line are on too (I have black square). Second line is off (nothing display).

I have adjust the 10k pot on the board.
